Experimental equipment for simulating rainfall

Abstract

The invention discloses experimental equipment for simulating rainfall. The experimental equipment comprises a main body frame, a water tank, a side slope inclined plate, an adjustable flow pump, an adjustable supporting frame, a water flow main pipeline, a rapid series-connection type flow dividing connector, a sliding groove and rain spraying heads. The water tank is arranged at the bottom of the main body frame and is provided with the side slope inclined plate; the inclination of the side slope inclined plate is adjusted by an adjustable support frame below the side slope inclined plate; the top of the main body frame is provided with the rapid series-connection type flow dividing connector and the sliding groove, and a plurality of rain spraying heads are installed in the sliding groove and can freely slide in the sliding groove. The rain spraying head is communicated with the rapid series-connection type flow dividing connector; one end of the water flow main pipeline is connected with the water tank, and the other end is connected with the rapid series-connection type flow dividing connector; the adjustable flow pump is mounted on the water flow main pipeline at the outlet of the water tank; and a flow meter is mounted on the water flow main pipeline. The rainfall intensity, density and uniformity can be adjusted, slope related tests are strengthened, the difference between the slope related tests and the actual rainfall condition is shortened, and the accuracy of the test result is high.

Description

technical field [0001] The invention relates to laboratory simulation experiment equipment, in particular to an experiment equipment for simulating rainfall. Background technique [0002] At present, there is a large gap between the artificial rainfall simulated in the laboratory and the actual rainfall situation. The gap between the two is mainly reflected in the uncontrollable rainfall intensity of the indoor rainfall device, the poor uniformity of rainfall, and the uncontrollable impact speed of rainfall. It directly affects the accuracy of the experimental results. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical problems, and provide a kind of experimental equipment for simulating rainfall. During the test, the slope of the side slope can also be adjusted, which shortens the gap with the actual rainfall and increases the accuracy of the experimental results. [0004] The technical solution for realizin...
